  DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Exemplary embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

(Structure of high altitude safety support device)
First, the configuration of a high-altitude safety support device according to an embodiment of the present invention will be described. FIG. 1 is an explanatory diagram showing a configuration of a high-altitude safety support device according to an embodiment of the present invention. In FIG. 1, the high-altitude safety support device 100 includes a safety belt 101 and a trunkless monitoring device (see FIG. 2) provided integrally with the safety belt 101.

  The safety belt 101 includes a torso belt 102 which is wrapped around a body (a waist, see FIG. 5) of a wearer such as an operator. The torso belt 102 is a wide band-shaped member, and is formed of, for example, a synthetic fiber such as nylon. The body belt 102 is provided with an auxiliary belt 103 that is a belt-shaped member wider than the body belt 102 in order to reduce the burden on the waist of the wearer.

  A buckle 104 is provided at one end in the length direction of the trunk belt 102. A stop metal fitting 105 is provided at the other end in the length direction of the torso belt 102. The torso belt 102 can be fixed to the wearer's torso by passing the front stopper 105 through the buckle 104 while being wound around the wearer's torso. The body belt 102 is provided with a belt loop 106 at one or more locations along the length of the body belt 102.

  A lanyard 107 is connected to an intermediate portion in the length direction of the trunk belt 102. The lanyard 107 includes a rope 108, a hook 109, and a telescopic adjuster 110. The rope 108 can be realized by, for example, a synthetic fiber using nylon or the like.

  A figure-shaped ring 111 is provided at an intermediate portion in the length direction of the rope 108. In the present embodiment, the annular member according to the present invention can be realized by the figure eight ring 111. The figure eight ring 111 has a substantially “8” shape including two integrated rings and is formed using a metal material. By hooking the hook 109 on the figure-eight ring 111 while the rope 108 is being wrapped around the structure, a single hanging state can be achieved.

  The rope 108 is provided with a linear conductor (see FIG. 2) that is continuous from one end to the other end. Specifically, such a rope 108 is formed, for example, by passing a conductor through the inside of a synthetic fiber constituting the rope 108, twisting a synthetic fiber with the conductor as a core material, or forming a linear shape on a part of the synthetic fiber. By twisting the rope 108 by mixing the above conductors.

  The hook 109 is provided at one end in the length direction of the rope 108. The hook 109 has a ring shape that can be partially opened and closed, and is formed using a metal material such as stainless steel. A part of the ring-shaped hook 109 that can be opened and closed is normally urged in a direction to close the ring by an urging member such as a spring (not shown).

  The hook 109 is used by being hooked on a structure such as a steel tower when working at heights. Specifically, when working at heights, the hook 109 is hooked on a structure such as a steel tower, and the wearer is connected to the structure such as a steel tower via the safety belt 101, so that the safety belt 101 is attached to the structure. It is possible to prevent the worker who performs the work from dropping and to perform the work safely.

  The telescopic adjuster 110 is provided at an intermediate position in the length direction of the rope 108. The expansion and contraction adjuster 110 includes a pair of claw members provided so as to sandwich the rope 108. The claw member receives a biasing force from a biasing member such as a spring (both are not shown). As a result, sliding of the telescopic adjuster 110 with respect to the rope 108 is restricted (locked), and is fixed to the rope 108.

  The expansion / contraction adjuster 110 includes an operation unit in which a pair of claw members are rotatably connected, and when the operation unit is urged in a predetermined direction, the claw member is turned against the urging force of the spring. To release the restriction (lock) of the rope 108. When the regulation (lock) of the rope 108 is released, the telescopic adjuster 110 can slide along the length direction of the rope 108.

  Thereby, for example, when moving the work place, the worker changes the position of the telescopic adjuster 110 with respect to the rope 108 and adjusts the length of the rope 108 between the telescopic adjuster 110 and the hook 109. This allows the user to move to an arbitrary work position while using the safety belt 101 without hindering the work.

  The torso belt 102 is provided with an annular member (hereinafter, referred to as a “D ring”) such as a D ring (rolip ring) 112. The D ring 112 has an alphabetical “D” shape and is formed using a metal material. In the operation using the safety belt 101, the hook 109 can be hooked on the D ring 112 while the rope 108 is wrapped around the structure, so that a U-shaped hanging state can be achieved.

  The bodyless monitoring device includes a housing 113 containing various circuits (see FIG. 2), a first IC chip 114, a second IC chip 115, a first antenna (see FIG. 2), 2 antennas (see FIG. 2), an interrogator (see FIG. 2), and the like. The housing 113 is provided at the other end in the length direction of the rope 108, that is, at the end opposite to the hook 109 with the expansion / contraction adjuster 110 interposed therebetween.

  The first IC chip 114 and the first antenna are provided on the figure eight ring 111. Specifically, for example, a seal-like member provided with the first IC chip 114 and the first antenna is attached to the figure-shaped ring 111 on the other side of the sheet having the adhesive layer on one side. , The first IC chip 114 and the first antenna can be attached to the figure eight ring 111.

  The second IC chip 115 and the second antenna are provided on the D ring 112. Specifically, for example, by attaching a seal-like member provided with the second IC chip 115 and the second antenna to the D ring 112 on the other surface of the sheet having the adhesive layer on one surface, The second IC chip 115 and the second antenna can be attached to the D ring 112. The interrogator is provided on the hook 109. One end of a conductor provided on the rope 108 is connected to a circuit in the housing 113, and the other end is connected to an interrogator.

(Hardware configuration of the bodyless monitoring system)
Next, the hardware configuration of the trunkless monitoring device will be described. FIG. 2 is an explanatory diagram illustrating a hardware configuration of the trunkless monitoring device. In FIG. 2, the trunkless monitoring device 200 includes a first IC chip 114, a second IC chip 115, a first antenna 201, a second antenna 202, an interrogator 203, and a trunkless rope detection. The circuit 204 includes a circuit 204, a GPS receiver 205, a zero switch 206, an altitude determination circuit 207, and a vibration motor 208. The GPS receiver 205, the trunkless detection circuit 204, and the vibration motor 208 are housed in a housing 113 and attached to the trunk belt 102.

  Each of the first IC chip 114 and the second IC chip 115 includes a power supply unit, a CPU, and a memory (all are not shown). The power supply unit converts an AC voltage generated when the antennas 201 and 202 of the first IC chip 114 and the second IC chip 115 are positioned in an AC magnetic field to a DC voltage, and further converts the AC voltage to a lower voltage. Supply to CPU.

  Each of the first IC chip 114 and the second IC chip 115 includes a CPU and a memory, and executes various processes using programs and data stored in the memory. The first IC chip 114 and the second IC chip 115 can be realized by, for example, an IC chip having a size of several millimeters square and a thickness of several hundred micrometers in plan view.

  The first antenna 201 and the second antenna 202 can be realized, for example, by a loop antenna in which a conductor (element) forms a loop shape (coil shape). The first antenna 201 is electrically connected to the first IC chip 114. The second antenna 202 is electrically connected to the second IC chip 115. Thus, the first IC chip 114 and the second IC chip 115 can communicate with the interrogator 203, respectively.

  The first IC chip 114 and the second IC chip 115 are activated by the induced power generated in the coil when the magnetic flux oscillated from the interrogator 203 passes inside the coil formed by the loop antenna and received from the interrogator 203. A magnetic field (a demagnetizing field) opposite to the magnetic flux is generated, and a data signal obtained by modulating the demagnetizing field as a carrier wave is output.

  The interrogator 203 includes a CPU, a memory, a clock oscillation circuit, a modulation circuit, a demodulation circuit, an amplification circuit, and an antenna (all are not shown). Under the control of the CPU, the interrogator 203 modulates a signal of a predetermined frequency generated by the clock oscillation circuit in the modulation circuit, amplifies the signal in the amplification circuit, and outputs the amplified signal to the outside via the antenna. Thereby, an AC magnetic field of a predetermined frequency can be generated around the interrogator 203.

  Specifically, the interrogator 203 generates an AC magnetic field having a predetermined frequency in a predetermined range from the antenna. Specifically, the predetermined range can be set to, for example, about 10 cm. Thus, power can be supplied to the first IC chip 114 and the second IC chip 115 positioned in the AC magnetic field.

  The interrogator 203 receives a data signal output from the first IC chip 114 or the second IC chip 115 via an antenna under the control of the CPU, amplifies the received signal in an amplifier circuit, and amplifies the signal. The demodulated signal is demodulated in the demodulation circuit. Upon receiving a signal output from the first IC chip 114 or the second IC chip 115, the interrogator 203 outputs a signal “1 (H)” to the no-branch detection circuit 204.

  That is, the interrogator 203 outputs a signal of “1” to the no-branch detecting circuit 204 when the hook 109 is located within a predetermined range from the figure-shaped ring 111 or the D-shaped ring 112. The interrogator 203 outputs a signal of “0 (L)” to the no-branch detection circuit 204 when, for example, the signal output from the first IC chip 114 or the second IC chip 115 is not received. (Or output no signal).

  The interrogator 203 outputs a signal of “1” to the no-branch detecting circuit 204 when a signal output from the first IC chip 114 or the second IC chip 115 is continuously received for a predetermined time. You may make it. Thereby, when the hook 109 is continuously within a predetermined range from the figure-shaped ring 111 or the D-ring 112 for a predetermined time, a signal of “1” is output from the interrogator 203 to the no-bore detecting circuit 204. I do.

  The predetermined time can be arbitrarily set by a designer or an operator of the no-maintained rope monitoring device 200. Specifically, the predetermined time is, for example, “10 seconds”, “15 seconds”, or the like, when the hook 109 held by the operator accidentally falls within a predetermined range from the figure-shaped ring 111 or the D-shaped ring 112. Instead of being located, the hook 109 can be set to a length at which it can be determined that the hook 109 has been hooked on the figure eight ring 111 or the D ring 112.

  The GPS receiver 205 includes a GPS antenna, an RF (Radio Frequency) unit, a baseband unit, and the like. The GPS antenna receives a radio wave transmitted from a GPS satellite. The RF unit demodulates the unmodulated signal received by the GPS antenna into a baseband signal.

  Based on the baseband signal demodulated by the RF unit, the baseband unit has a height at which the no-mainline monitoring device 200 is currently located, that is, a height at which the worker wearing the high-altitude safety assurance support device 100 is currently located. Is calculated. The baseband unit performs positioning by calculating distances to the four GPS satellites and calculating a position where each distance intersects one. The GPS receiver 205 outputs the calculated height to the altitude determination circuit 207.

  The zero switch 206 can be realized by, for example, a normally open momentary type push button switch. The zero switch 206 has a contact (a contact) that closes the circuit when operated (pushed), and outputs a signal to the altitude determination circuit 207 while the circuit is closed.

  The altitude determination circuit 207 determines whether or not the height of the safety belt 101 from a reference height such as the ground is equal to or less than a predetermined threshold. The altitude determination circuit 207 includes a memory, and upon receiving a signal output from the zero switch 206, stores the height calculated by the GPS receiver 205 at the time of the operation as a reference height in the memory. .

  The altitude determination circuit 207 calculates a difference between the height calculated by the GPS receiver 205 and the reference height stored in the memory, and when the calculated difference exceeds a predetermined threshold value, A signal “1” is output to the detection circuit 204. If the difference between the height calculated by the GPS receiver 205 and the reference height stored in the memory does not exceed a predetermined threshold, the altitude determination circuit 207 outputs “0” to the no-breast detecting circuit 204. Output a signal (or do not output a signal).

  The predetermined threshold value can be arbitrarily set by a designer or an operator of the trunkless monitoring device 200. Specifically, for example, the predetermined threshold value is set to a value of a height that is supposed to impair the human body when dropped from a height exceeding the predetermined threshold value, such as “2 meters”. Can be.

  Alternatively, specifically, the predetermined threshold is, for example, the height of the high place safety assurance support device 100 in a state that the worker is wearing, that is, considering the height from the feet of the worker to the waist, for example, , “2.5 meters”. In this embodiment, the height detector according to the present invention can be realized by the GPS receiver 205, the zero switch 206, the altitude determination circuit 207, and the like.

  The trunkless line detection circuit 204 determines whether or not the vehicle is in a trunkless state based on output signals from the interrogator 203 and the altitude determination circuit 207. The trunkless line detection circuit 204 receives a signal output from the interrogator 203 via a conductor 210 provided on the rope 108. In this embodiment, the no-class line detection circuit 204 can implement the no-class class state determination unit according to the present invention.

  Specifically, the trunkless detection circuit 204 determines that the height at which the trunkless monitoring device 200 is currently located, that is, the height at which the worker wearing the high-altitude safety assurance support device 100 is currently located is the reference height. Is determined to be in a trunkless state when the signal from the first IC chip 114 or the second IC chip 115 is not received. When the bodyless line detection circuit 204 determines that the vehicle is in the bodyless state, it outputs a drive signal to the vibration motor 208.

  When the interrogator 203 receives a signal output from the first IC chip 114 or the second IC chip 115 continuously for a predetermined time, the interrogator 203 outputs a signal of “1” to the no-class detection circuit 204. In the case of the specification, the trunkless detection circuit 204 determines that the height at which the worker wearing the high-altitude safety assurance support device 100 is currently located is equal to or more than the predetermined height from the reference height, and If a signal output from the IC chip 114 or the second IC chip 115 has not been continuously received for a predetermined period of time, it is determined that the vehicle is in a trunkless state.

  In other words, the trunkless line detection circuit 204 outputs the signal of “1” from the altitude determination circuit 207 and the signal of “1” from the first IC chip 114 or the second IC chip 115 continues for a predetermined time. Is not output, it is determined that the vehicle is in the state of no trunk.

  If the interrogator 203 is designed to always output a signal of “1” to the no-branch detecting circuit 204 when the interrogator 203 is located within a predetermined range from the figure-eight ring 111 or the D-ring 112, The circuit 204 may output the signal “1” to the vibration motor 208 when the signal “1” output from the interrogator 203 is continuously received for a predetermined time.

  In this case as well, the trunkless line detection circuit 204 determines that the height at which the worker wearing the high-altitude safety assurance support device 100 is currently located is equal to or more than the predetermined height from the reference height, and the first IC When the signal of “1” is not continuously output from the chip 114 or the second IC chip 115 for a predetermined time, it is determined that the vehicle is in the trunkless state.

  The vibration motor 208 operates in accordance with the drive signal output from the trunkless line detection circuit 204. The vibration motor 208 includes a rotor (magnet) rotatable around the axis and a fixed stator (stator). In the vibration motor 208, the centers of the rotor and the stator do not coincide with each other and are eccentric. Therefore, vibration can be generated by rotating the rotor.

  The vibration motor 208 outputs a drive signal output from the no-bore detection circuit 204 when the no-bore detection circuit 204 determines that the safety belt 101 is in a no-bore state at a height equal to or higher than a predetermined threshold. Operate accordingly. Specifically, the vibration motor 208 operates when a signal indicating “1” is output from the trunkless line detection circuit 204. The vibration motor 208 switches while the signal indicating “1” is being output from the no-class detection circuit 204, that is, the signal output from the no-class detection circuit 204 is switched to “0” (or the signal is output). It is preferable that the operation continues.

  In this embodiment, the notification unit according to the present invention can be realized by the vibration motor 208. By notifying by a vibration that the user is working at a height equal to or higher than a predetermined threshold from the ground, it is possible to easily and reliably alert the worker even in a work site where sound is hardly transmitted due to noise or the like.

  The bodyless monitoring device 200 replaces the GPS that determines the geometric position between the GPS satellite and the GPS receiver 205 based on the radio wave received from the GPS satellite, and replaces the Michibiki (registered trademark), GLONASS, and Galileo. (Galileo) or another satellite positioning system may be used to specify the height at which the worker wearing the high-altitude security support apparatus 100 is currently located.

  In addition, the bodyless monitoring device 200 uses the barometric altimeter instead of the GPS receiver 205, and the height at which the bodyless monitoring device 200 is currently located, that is, the work in which the high altitude safety support device 100 is mounted. The height at which the person is currently located may be calculated.

  In addition, the trunkless monitoring device 200 includes a power supply not shown. The power supply is housed in the housing 113 together with the GPS receiver 205, the trunkless circuit detection circuit 204, and the vibration motor 208. The power supply supplies power to the interrogator 203 and the GPS receiver 205. The power supply supplies power to the interrogator 203 via a conductor 210 provided on the rope 108. Specifically, for example, various batteries can be used as the power supply.

(An example of the no-cord detection circuit 204)
Next, an example of the trunkless line detection circuit 204 will be described. FIG. 3 is an explanatory diagram illustrating an example of the trunkless line detection circuit 204. As shown in FIG. 3, the trunkless line detection circuit 204 can be realized by an AND circuit having two input terminals and one output terminal.

  A signal output from the altitude determination circuit 207 is input to one of two input terminals included in the AND circuit. A signal output from the interrogator 203 is input to the other input terminal of the two input terminals included in the AND circuit.

  The output terminal of the AND circuit is connected to the vibration motor 208. The AND circuit outputs a signal indicating “1” to the vibration motor 208 via the output terminal only when all signals input from both of the two input terminals are “1”. The AND circuit outputs “0” (or does not output a signal) when “0” is input to at least one of the two input terminals.

  Accordingly, when the altitude determination circuit 207 determines that the difference has exceeded the predetermined threshold value and determines that the vehicle is in the state of a trunkless body based on the output signal from the interrogator 203, the AND circuit sends a signal to the vibration motor 208. By outputting a signal indicating “1”, the vibration motor 208 can be operated.

(Judgment pattern of the trunkless circuit detection circuit 204)
Next, a description will be given of a determination pattern of the trunkless line detection circuit 204.

(How to use the high altitude safety support device 100)
Next, a method of using the high-altitude security support apparatus 100 will be described. First, the worker using the high-altitude security support device 100 wears the high-altitude security support device 100, that is, the safety belt 101. As described above, since the high-altitude safety support device 100 has the safety belt 101 and the no-mainline monitoring device 200 integrally provided, the high-altitude safety maintenance is performed by the usual operation of mounting the safety belt 101. The support device 100, that is, the safety belt 101 and the non-mainline monitoring device 200 can be mounted.

  The worker wearing the high-altitude safety support device 100 operates the zero switch 206 before climbing to a steel tower or the like, that is, on the ground. Thereby, the reference height in the altitude determination circuit 207 is reset, and the position where the zero switch 206 is operated, that is, the ground is stored in the memory in the altitude determination circuit 207 as the reference height (0 m).

  More specifically, by operating the zero switch 206 with the worker wearing the high-altitude safety support device 100, the height of the high-altitude safety support device 100 worn by the worker from the ground is The height is stored in the memory of the altitude determination circuit 207 as the reference height (0 meters). Thus, when setting a predetermined threshold value in the memory of the altitude determination circuit 207, the height safety support device 100 can be set without considering the height of the height safety support device 100 worn by the worker. It is possible to determine that the worker is located at a height equal to or higher than a predetermined height (2 meters) regardless of the height or the like of the worker wearing the.

  In this state, when the worker climbs a tower such as a steel tower, the GPS receiver 205 always calculates the height and outputs the calculated height to the altitude determination circuit 207. The altitude determination circuit 207 calculates a difference between the height calculated by the GPS receiver 205 and the reference height stored in the memory, and when the calculated difference exceeds a predetermined threshold, a no-class detection circuit. A signal of “1” is output to 204.

  In parallel with the operations of the GPS receiver 205 and the altitude determination circuit 207, the interrogator 203 determines whether a signal output from the first IC chip 114 or the second IC chip 115 has been received. When a signal output from the first IC chip 114 or the second IC chip 115 is received, a signal “1” is output to the no-branch detecting circuit 204.

  The no-cord detection circuit 204 determines, based on the output signals from the interrogator 203 and the altitude determination circuit 207, the height at which the worker wearing the high-altitude security assisting device 100 is currently located is a predetermined height from the reference height. When the state where the hook 109 is not located within the predetermined range from the figure-shaped ring 111 or the D-ring 112 has continued for a predetermined period of time, it is determined that the state is the trunkless state, and the vibration motor 208 is determined. Output a signal indicating "1".

(Example of judgment by the high-altitude safety support device 100)
Next, a description will be given of an example of determination by the high-altitude security support apparatus 100. FIG. 5 is an explanatory diagram illustrating an example of a determination made by the high-altitude security support apparatus 100. As shown in FIG. 5, when the worker operates the zero switch 206 at the position A, that is, when the operator is on the ground, the altitude determination circuit 207 outputs a “0” signal to the no-branch detection circuit 204. . At this time, when the hook 109 is not hooked on the figure eight ring 111 or the D ring 112, the interrogator 203 outputs a signal of “1” to the no-branch detecting circuit 204.

  In this case, the trunkless line detection circuit 204 outputs a signal indicating “0” to the vibration motor 208 (or does not output the signal), and the vibration motor 208 does not operate. Accordingly, the vibration motor 208 is operated only when the safety belt 101 is in the state of a trunkless body at a height equal to or higher than the predetermined threshold, and it is possible to avoid troublesome operation of the vibration motor 208 excessively.

  When the worker is at the position B, that is, at a position lower than the height of 2 meters from the ground, the altitude determination circuit 207 outputs a signal “0” to the no-branch detection circuit 204. At this time, if the hook 109 is not hooked on the figure eight ring 111 or the D ring 112, the interrogator 203 outputs a signal of “1” to the no-branch detecting circuit 204.

  In this case, the trunkless line detection circuit 204 outputs a signal indicating “0” to the vibration motor 208 (or does not output the signal), and the hook 109 is hooked on the figure-shaped ring 111 or the D-shaped ring 112. If not, the vibration motor 208 does not operate. Accordingly, the vibration motor 208 is operated only when the safety belt 101 is in the state of a trunkless body at a height equal to or higher than the predetermined threshold, and it is possible to avoid troublesome operation of the vibration motor 208 excessively.

  When the worker is at the position of C or D, that is, at a position higher than 2 meters from the ground, the altitude determination circuit 207 outputs a signal of “1” to the no-branch detection circuit 204. At this time, when the hook 109 is hooked on the figure eight ring 111 or the D ring 112, the interrogator 203 outputs a signal “0” to the no-branch detecting circuit 204. In this case, since the worker is using the safety belt 101 at a position at a height of 2 meters or more from the ground, the no-branch detection circuit 204 outputs a signal indicating “0” to the vibration motor 208. (Or does not output a signal), and the vibration motor 208 does not operate (see the position C in FIG. 5).

  On the other hand, if the hook 109 is located at a height of 2 meters or more from the ground and the hook 109 is not hooked on the figure-eight ring 111 or the D-ring 112, the interrogator 203 outputs a signal of “1” to the no-body class detection circuit 204. Is output. In this case, the trunkless line detection circuit 204 outputs a signal indicating “1” to the vibration motor 208. Thus, the vibration motor 208 operates to notify the worker that the vehicle is in the state of the trunkless at a height of 2 meters or more from the ground.

  The no-cord detection circuit 204 determines, based on the output signals from the interrogator 203 and the altitude determination circuit 207, the height at which the worker wearing the high-altitude security assisting device 100 is currently located is a predetermined height from the reference height. Even with the above, when the hook 109 is located within a predetermined range from the figure-eight ring 111 or the D-ring 112, it is determined that the vehicle is not in the no-brass state, and “0” is output (or a signal is output). Is not output). Thus, the vibration motor 208 can be operated only when the safety belt 101 is in the state of the trunkless at a height equal to or higher than the predetermined threshold.

  The no-cord detection circuit 204 determines, based on the output signals from the interrogator 203 and the altitude determination circuit 207, the height at which the worker wearing the high-altitude security assisting device 100 is currently located is a predetermined height from the reference height. If not, even if the hook 109 is not located within a predetermined range from the figure-shaped ring 111 or the D-ring 112, it is determined that the hook 109 is not in the state of no trunk, and “0” is output (or a signal is output). No output). Accordingly, when the safety belt 101 is working at a height lower than the predetermined threshold, it is possible to avoid operating the vibration motor 208 excessively.

  Based on the difference between the height calculated by the GPS receiver 205 and the height calculated by the GPS receiver 205 when the zero switch 206 is operated (reference height), The height at which the worker wearing the high-altitude safety assurance support device 100 is currently located is detected. That is, based on the difference between the heights calculated by the single GPS receiver 205, the height at which the worker wearing the high-altitude security support apparatus 100 is currently located is detected.

  By using the GPS receiver 205, it is assumed that a noise that is an error factor that fluctuates in a short time or a bias that is an error factor that persists for a certain amount of time causes a height calculation error. By specifying the ground height at which the worker is located on the basis of the difference from the reference height as described above, the GPS receiver 205 calculates, for example, due to the presence of an obstacle such as a tree or a building. Even when the height to be shifted is different from the original height, the difference between the shifted heights can be specified as the ground height at which the worker is located.

  Thus, the ground clearance at which the worker is located can be accurately specified without being affected by the work environment. With this, it is possible to accurately notify the worker that the safety belt 101 is in a state of no trunk at a height equal to or higher than the predetermined threshold value, and to increase the safety of the worker without putting a burden on the worker. Can be enhanced.
